Hello :
<span>5cosθ = 3cosθ - 1.
</span><span>5cosθ - 3cosθ = 1.
2cos</span>θ =1
cosθ =1/2
all solutions :
cosθ =cos<span>π<span>/3
</span></span>all solutions :
θ =π/3 +2kπ or θ = - π/3 +2kπ ....k in Z
Remember that

is

. We know form our problem that

and

, so:



Now, to find

, we just need to evaluate

at 3. In other words, we are going to replace

with 3:


We can conclude that the correct answer is <span>
C.6(3) – 4 + 3^2 </span>
